At HEM Motor we do not merely supply electric motors; we manufacture them in our own facility and ship them from stock. An electric motor is the workhorse that turns grid electricity into a rotating shaft to drive your machine, and in this category you benefit both from the engineering know-how of a maker and from the wide stock and quick dispatch of a supplier.
Our portfolio reaches from small workshop powers to the high-power demands of heavy industry. On the efficiency side we cover IE3, IE4 and IE5; on the body side cast iron and lightweight options; and on the drive side different pole counts, all under one roof. Our motors are built with IP55 protection and Class F insulation, with slip near 4% around full load.
Choosing the right motor the first time affects both the initial outlay and years of running electricity cost. If you are unsure which power and speed suit your job, our engineering team advises based on your application.

When you start an asynchronous motor for the first time, the motor draws, for a brief moment, a current far above the rated current. This high initial current is called the startin... More Details
When it comes to carrying pressurized water from an apartment building's water tank up to the top floor, feeding a high-pressure washing line in an industrial plant, or raising the... More Details
When an electric motor arrives on site, one of the first things to do is to lower, handle and place it safely at the installation point. This seemingly simple step is actually a cr... More Details
Consider two IE3 motors: both rated at the same kW power, both in the same efficiency class, both from the same brand. Intuitively, you would say "they do the same job." Yet these ... More Details
Selecting the main drive motor of a ball or rod mill in a mineral processing plant, cement factory or ore grinding line is very different from an ordinary motor selection. A mill l... More Details
Knowing which of the dozens of motors in a facility comply with the current efficiency regulation is a critical question both for legal compliance and for energy cost. The answer t... More Details
Can there be two different motors in the same efficiency class? Yes. The IE4 Super Premium efficiency class can be achieved both with classic asynchronous (squirrel-cage) motors an... More Details
When selecting a motor for a machine operating under heavy shock loads such as a crusher, press or mill, the most frequently debated topic is the frame material. The reason cast ir... More Details
The most common mistake when ordering an IE5 synchronous reluctance (SynRM) motor is to think of it like a classic asynchronous motor. In fact, IE5 synchronous reluctance motors ma... More Details
When you buy an electric motor, the first number on the nameplate is usually the purchase price; yet the real cost of that motor to your facility over its lifetime goes far beyond ... More Details
One of the most effective ways to cut the energy bill in pump and fan plants is, instead of running the motor at fixed speed and throttling the flow with a valve, to reduce the mot... More Details
"Should I switch to an IE4 motor, or is IE3 enough?" is one of the most frequent questions businesses ask in this period of rising energy costs. The correct answer is not always "t... More Details
Selecting an electric motor in food, beverage and pharmaceutical plants is very different from selecting an ordinary industrial motor. In these plants the line is washed at the end... More Details
When buying an asynchronous motor, most businesses carefully study the power (kW) and efficiency class (IE3/IE4) but overlook the "cos phi" value on the nameplate. Yet the power fa... More Details
When buying an asynchronous motor, the labels "insulation class: F" and "temperature rise: B (80K)" on the nameplate tell you far more than the rated power figure. These two values... More Details
If you want a fan to run at two stages, "fast" and "slow," an elevator to slow down as it approaches a floor, or a conveyor to carry material at two different speeds, and you do no... More Details
If you find yourself asking "why does this drive need such a low speed?" on a mixer, a cooling tower fan or a slow-rotating large drum, the answer is very often a 12-pole very low ... More Details
400 and 450 kW electric motors represent the top class of the low-voltage asynchronous motor range. These powers are no longer products taken off a shelf and delivered; they are pr... More Details
There is only a twenty-five percent power gap between 200 kW and 250 kW; but this relatively small difference seriously changes the motor's frame size, weight and delivery process.... More Details
1.5 kW and 2.2 kW are the two most-used mid-range power classes in industry; from pumps to fans, from conveyors to small machines, you encounter these motors in countless applicati... More Details
